simpleperf: exclude kernel callchains when needed. Exclude kernel callchains when users only monitor events in user space. After this change, when users use `record -e cpu-cycles:u --trace-offcpu`, the samples of the implicitly added sched:sched_switch event won't contain any kernel callchain. Bug: http://b/37572306 Test: run simpleperf_unit_test. Change-Id: Iffcb61bac796e734825e68f847f24b4006b44360
